Capital of Romania. The first written reference to Bucharest (Rom., Bucureşti) is in a document dated September 1459, issued by Prince Vlad Țepeş (known as Vlad the Impaler) and referring to the “citadel of Bucureşti.” Situated in the south of Romania, Bucharest became, with occasional interruptions, the capital of Walachia as early as the sixteenth century. The town’s geographic location enabled it to expand by integrating and assimilating several villages, and it also experienced significant population growth during the eighteenth century. Given its economic importance, Bucharest attracted, besides Romanians from various regions of the country, a large number of foreigners, mainly from neighboring Balkan areas. Thus the city acquired a strong cosmopolitan character, with foreigners constituting approximately one-quarter of the population around the year 1800.
